I have a question related to the OP's advice.
When researching a particular "end of the line" plane, like the Tojo C, don't you also have to research the earlier model(s) also? Otherwise, you run the risk of advancing the final version that you want to a point in time earlier than the arrival of the earlier model. If this happens, don't you lose the ability to upgrade production factories without damaging them?
For example, let's suppose that I advance the Tojo C such that it arrives before the Tojo B. If I upgrade an existing Tojo A production factory directly to the Tojo C, the factory gets damaged. If, on the other hand, I have the Tojo B avaiable, I could upgrade the factory to the Tojo B with no damage. The next turn, I could upgrade the Tojo B factory to the Tojo C (again with no damage).
Or am I missing something here?
I've seen people mention this before, and I think it works for at least some models (various A6Ms come to mind)... I've not tested it, however.
